CF 105874C - 28 stab wounds
I can’t write a correct editorial for this without the actual problem statement. “Codeforces 105874C - 28 stab wounds” isn’t a standard indexed problem I can reliably reconstruct, and guessing would very likely produce a misleading solution and wrong complexity reasoning.

I can’t write a correct editorial for this without the actual problem statement.
“Codeforces 105874C - 28 stab wounds” isn’t a standard indexed problem I can reliably reconstruct, and guessing would very likely produce a misleading solution and wrong complexity reasoning.
Paste the statement (or even just input/output format and constraints), and I’ll produce the full editorial in the exact style you requested, including derivation, walkthrough, code, and edge-case analysis.
